Support for Rollbacks Rollbacks are only supported by the SUSE support if you do not remove any of the preconfigured subvolumes. You may, however, add additional subvolumes using the YaST Partitioner. Use the compress or compress-force option and select the compression algorithm, lzo or zlib the default.
The zlib compression has a higher compression ratio while lzo is faster and takes less CPU load. If you do not like this behavior, use the compress-force option. This can be useful for files that have some initial non-compressable data. Note, compression takes effect for new files only. Files that were written without compression are not compressed when the file system is mounted with the compress or compress-force option.
Furthermore, files with the nodatacow attribute never get their extents compressed: After you have written some data to this partition, print the details: This allows you to check the snapshot while running before doing the rollback. Being able to boot from snapshots is achieved by mounting the subvolumes which would normally not be necessary.
The other subvolumes will be mounted into this volume.
When booting from a snapshot, not the subvolume will be used, but rather the snapshot. The other subvolumes will be mounted writable into the snapshot. This state is temporary by default: To make it permanent, execute the snapper rollback command.Linux Tutorial for Beginners - 19 - Creating Partitions with GParted
This will make the snapshot that is currently booted the new default subvolume, which will be used after a reboot. On a Btrfs file system, the output of df can be misleading, because in addition to the space the raw data allocates, a Btrfs file system also allocates and uses space for metadata. Consequently a Btrfs file system may report being out of space even though it seems that plenty of space is still available.
In that case, all space allocated for the metadata is used up. Use the following commands to check for used and available space on a Btrfs file system: If these two values in the last line match, all space on the file system has been allocated. If the values for total and used for the metadata are almost equal, all space for metadata has been allocated. For more information refer to man 8 btrfs-filesystem and https: The conversion process occurs offline and in place on the device. To convert the file system to Btrfs, take the file system offline, then enter: Either keep the existing file system or re-install the whole system from scratch.
Possible Loss of Data When rolling back to the original file system, all data will be lost that you added after the conversion to Btrfs. That is, only the original data is converted back to the previous file system.

It is available during the installation to allow you to set up a solution for the root file system. Btrfs administration tools are provided in the btrfsprogs package. For information about using Btrfs commands, see the man 8 btrfs, man 8 btrfsck, and man 8 mkfs. In these cases, swap will be used to help the system handle any extra load. Hibernation suspend-to-disk The hibernation feature suspend-to-disk writes out the contents of RAM to the swap partition before turning off the machine.
Therefore, your swap partition should be at least as big as your RAM size. The hibernation implementation currently used in Ubuntu, swsusp, needs a swap or suspend partition.
It cannot use a swap file on an active file system. Unforeseeable Circumstances Unforeseeable events can and will happen a program going crazy, some action needing much more space than you thought, or any other unpredictable combination of events.
In these cases, swap can give you an extra delay to figure out what happened, or to finish what you are working on. Optimizing memory usage Since mechanical hard drives are considerably slower than RAM SSD - Solid State Drive - storage is not as slow as physical drives, but still slower than RAMwhen you need a file be it a data file like a video, executables like Firefox, or librariesthe Linux kernel reads the file into RAM and keeps it there, so that the next time you need it, it is already in RAM and data access is much faster.
The portions of RAM that accelerate disk read are called "cached memory. The Linux kernel automatically moves RAM reserved by programs--but not really used--into swap, so that it can serve the better purpose of extending cached memory. Optimizing Swap performance Because swap space uses a disk device, this can cause performance issues in any system that uses swap space significantly because the system itself may also be using the same disk device at the same time that it is required for swap operations.
One way to reduce this problem is to have swap space on a different physical drive so that the competition for that resource is either reduced or eliminated. How much swap do I need? Also, it's recommended that the swap space is maximum twice the amount of RAM depending upon the amount of hard disk space available for the system because of diminishing returns.
[ubuntu] Can't resize extended partition woth gparted
The only downside to having more swap space than you will actually use, is the disk space you will be reserving for it. Swap is generally associated with a swap partition, perhaps because the user is prompted to create a swap partition at the time of installation. In fact, any file can be used as a swapping device, be it a partition or a conventional file.
Swap can be added by increasing the size of the swap partition or by adding a swap file.
Keep in mind that when creating a swap file that it may not necessarily be using contiguous disk blocks as a swap partition willand this could have a negative impact on performance as disk access times may be longer, and the more your system uses swap, the worse it will be. The Linux kernel also accesses swap disk block IO directly bypassing all caching, metadata and filesystem code, so a swap file should have no ill effect on the stability of your base filesystem.
The advantages of a swap file are many, but it is problematic for using the default swsusp hibernation method for powerless sleep. The best solution for maintaining hibernate capability after adding RAM is to increase the size of the swap partition. The power supply isn't strong enough. There's no OS installed. Check the SD card is properly in place and you've followed the instructions to write out the card.
Wrong edition of the Raspberry Pi.
The Raspberry Pi 3 Series needs a 2. PSUs that seemingly worked in the last have been seen to cause issues with Fedora 29 due to this. What desktop environments are supported? Will there be more enhancements to the hardware support Yes. New enhancements will be delivered when, and as soon as, they are ready via the standard Fedora updates mechanism.
New significate features will be blogged about as they arrive either via Fedora Magazine or the Fedora Planet. There's been a number of attempts to support these over the years. The current best effort is Pignus based on Fedora More information can be found at the Pignus site.
Support for the Compute Module 3 CM3 has landed upstream in the 4. There was a bug with WiFi on late 4. Bluetooth works quite well and seems to be quite stable. The device sometimes has a generic bluetooth address but should over all work just fine without any configuration. HDMI audio output is included Fedora however the analog port is not yet supported. Audio output via a USB audio interface should also work fine.
